| 中文摘要 |
| 本文讨论了一类具有不确定噪声的离散时间随机线性系统的鲁棒LQG问题，文章给出了确保控制性能的不确定噪声协方差矩阵的扰动上界，以及极小极大鲁棒LQG调节器的设计方法.采用这种调节器不仅能极小化不确定下的最坏性能，而且也能确保控制性能指标达到给定的自由度内。 |
| 英文摘要 |
| In the paper，the robust LQG problem for the discrete-time stochastic linear system with uncertain noise is considered. The perturbation upper bounds on uncertain noise covariances that guarantee control performance are obtained，and the design method of minimax robust LQG regulator is also given in the perturbation upper bounds.
In particular，it is shown that this regulator can minimize the worst performance in uncertain-case and guarantee control performance index to he within a given freedom. |
